ANTISLIP TILE.

Application filed January 25, 1922. Serial ma 531,171.

To all whom it may; concern:

Be it known that l. FRANK J. ToNu. a citizen of the United States. residing at Niagara Falls. in the county of Niagara and State of New York. have invented anew and useful Improvement in Antislip Tiles, of which the following is a full, clear, and ex: act description.

My invention relates to tiles. particularly those for floor surfaces, and is designed to provide an improved type of tile which overcomes disadvantages heretofore present in the use of abrasives for giving a non-slip surface.

To that end. my. invention consists in forming a molded. shaped and preferably burned tile. a certain percentage of the tile mixture being formed of fragments, which fragments are formed by crushing or breaking up a block formed of bonded together abrasive granules or grains.- By using these fragments or broken up particles of bonded grains, I have discovered that the grains are firmly retained in place in the tile and do not wear smooth and lose their non-slip properties. Such tiles may also be made in various :olors, especially light colors,.thus giving advantages in color eifects.

I will now describe a specific example of .my invention. I

One embodiment of my invention is illustrated in the accompanying drawing in which the figure shows a perspective view of a tile of block embodying the present invention.

In the drawing, 2 designates asuitable burned tile, slab or block of any desired shape having a tread face 3 in which are clusters of abrasive grains 4 bonded by a ceramic binder as hereinafter described.

A mixture is made of aluminous abrasive grains 7 6 parts. powdered feldspar 18 parts, and powdered kaolin 6 parts. In using the grit or abrasive, I preferably employ several sizes, the coarsest of which may be No. 60 and the finest 150. This mixture is moistened with water and thenpressed or otherwise molded into blocks or pieces of a size cpnvenient for subsequent crushing or breakmg up. The blocks are then referably dned and burned in a ceramic In at a temperature of about 1350 C. When removed from the kiln, the blocks are crushed into fragments which preferably range in size from to of an inch in thickness.

1 then make up a tile mixture of these bonded abrasive fragments, which may be as follows:

I Parts. Abrasive fragments 25 This mixture is then preferably moistened with water to the consistency required for dry pressing, and is then pressed into the form of tiles or tread pieces in ordinary tile presses. The tiles thus formed are then dried and burned, the burning preferably being carried out in a ceramic kiln at a temperature of about 1350 C.

The advantages of my invention result from the use of the bonded abrasive grain fragments in a tile. since the desired nonslip ualities are afforded; the color may be varie widely and light colors used; and the non-slip properties are retained in usage.

It Wlll be understood that while the above is one example of my invention, the abrasive emplo ed and both mixtures may be varied, as well as the method of making the blocks and tiles therefrom.

I claim:

1. As a new article of manufacture, a burned tile having in its tread surface clusters of abrasive gains previously bonded by a ceramic binder.

2. As a new article of manufacture, a burned tile having in its tread surface clus ters of abrasive grains previously bonded by a fired ceramic binder.

3. As a new article of manufacture, a 95 burned tile having in its tread surface clusters of abrasive grains previously bonded by a fired ceramic binder, the major portion of the total mass of the clusters being constituted of abrasive grains.

In testimony whereof I have hereunto set my hand.

FRANK J. TONE.
